根据灰色GM(1,1)预测模型预测某型航空活塞发动机进气门烧蚀变形量,并利用Mat LAB进行计算分析。结果表明,采用灰色预测理论进行预测分析,可以得到满意的预测精度,可以为该型发动机的维修提供一定的理论支持。
The ablation deformation of an aero-piston engine intake valve was predicted based on the gray GM (1,1) prediction model. Mat LAB was used for calculation and analysis. The results show that using gray prediction theory to predict and analyze can get satisfactory prediction precision and can provide some theoretical support for the maintenance of this type of engine.
